Benchmarks: Hyper threading performance

Up

In my own hyper-threading benchmark under SuSE (SLES 8) I saw a significant reduction in throughput when simultaneously using the primary and the 'virtual' processor. My benchmark is custom designed to emulate a processor intensive application that I run -- so, naturally, your mileage will vary.
Sandra's CPU benchmark is obviously quite optimized for hyperthreading at this point, and the numbers certainly show that. We see an average improvement of ~52.5% when hyper-threading is enabled on the P4 and an average improvement of ~28% with the Xeons. In the Dhrystone ALU, performance seemingly lags behind a little bit when HT is enabled but I could probably chalk that small percentage up to human error.
